The ISU is a very fun unit to use and I think it is know a very useful unit. I generally use it to breakthrough the toughest strong points or as just a counter to vet wehr armor or against the tank destroyer doctrine. I always surpport it with a wave of rb strelky and tank hunter cause it really needs its surpport otherwise its toast, vet 3 shreck grens seem to be best counter.
So just wondering why i rarely see it being used in 2v2 and if u do use whether u use it a a heavy tank destroyer, counter to jadg or kts, to break heavy defence or all of the above.
